911 Years of Microparticle Deposition at the South Pole: A Climatic Interpretation

A detailed analysis of the particles within a 101-meter firn core from Amundsen-Scott South Pole Station Antarctica, was conducted. 6218 samples were analyzed for particle concentration and size distribution. Individual particles within selected sections of the core were examined for morphology and...
